Abstract

This study was accomplished with the intention of developing a new strategy of conflict against the grubs of C pipiens, vectors of parasitical diseases, by bringing a major interest in the use of essential oils of plants as bio-insecticide. The method of job which we adopted, aimed at the valuation of the larvicide activity of the plant material of R officinalis in this species of mosquito collected from the MEKKERA wadi of the city of SIDI BEL ABBES. The results obtained show that the essential oil extracted from R officinalis manifested toxicity towards fourth-stage larvae in Culex pipiens, with a concentration-response relationship. Analysis of the data shows that R. officinalis causes a reduction in several morphometric parameters such as the width of the thorax, the weight and the body volume of the larval stage 4 individuals of C pipiens compared to the controls.
